Sheet supplying apparatus and printing apparatus
A sheet supplying apparatus, which is capable of winding a sheet tightly, includes a driving unit configured to cause a roll including a wound consecutive sheet to rotate in a first direction for feeding the sheet or a second direction opposite to the first direction, a sensor that detects a leading end portion of the sheet separated from an outer circumferential surface of the roll, and a contact body that presses the outer circumferential surface. Before the sheet is fed, in a state in which the contact body presses the outer circumferential surface, the driving unit causes the roll to continuously rotate in the second direction until a detection cycle of the leading end portion by the sensor is less than a predetermined value.

Printing device performing positioning of rotary body based on detection results from two detectors
A printing device includes: a motor; a rotary body driven by the motor to rotate; a movable blade driven by rotation of the rotary body to cut a printing tape; a gear mechanism provided on a power transmission path from the motor to the movable blade; a first detector outputting a first signal based on a rotated position of the rotary body; a second detector outputting a second signal based on the rotated position, and a controller performing positioning the rotary body to a predetermined reference rotated position. The positioning includes: starting rotating the rotary body in one direction on the basis of the first signal at the time of starting the positioning; halting the rotation in the one direction of the rotary body on the basis of the second signal; and rotating the rotary body in the opposite direction for a prescribed time period after the halting is completed.
Printing apparatus and printing method
A printing apparatus that includes a holding unit configured to hold a roll sheet performs supplying the sheet by rotating the roll sheet held by the holding unit; nipping and conveying the supplied sheet; performing printing on the conveyed sheet; detecting occurrence of a print medium jam of the sheet; and, if the printing apparatus has detected a print medium jam of the sheet, performing a control process of supplying the sheet in a state in which the conveying is stopped.
Forward and backward rotation of printer cutters
Disclosed is a cutter module to be used with a printing apparatus. The cutter module comprises a blade driving mechanism; and a rotary cutting blade driven by the blade driving mechanism. The blade driving mechanism comprises: a clutch mechanism selectively to enable the blade driving mechanism to drive the rotary cutting blade in a forward cutting direction or a backward direction. Also disclosed is a printing system comprising the cutter module and a method to be used with the cutter module.
Adjustable slitters for accurate transport-wise cutting of printed media
Various embodiments of systems and methods facilitate the calibration of a printer. The printer can print a calibration target and cut the calibration target using an inline slitter. The printer can determine a calibration offset based on the position of the cut on the calibration target. The printer can then be calibrated according to gross amounts on the slitter and fine amounts at an ink applicator.
Cutting device including cutter lever for moving cutter blade, and cutter cradle lever for moving both cutter blade and cutter cradle
A cutting device includes: a cutter blade configured to perform one of a half-cutting operation and a full-cutting operation with respect to a cut target; a cutter holder holding the cutter blade; a cutter cradle movable between a half-cutting position and a full-cutting position; and a cutter lever and a cutter cradle lever those operated by a user. When only the cutter lever is operated by the user, the cutter blade is moved so that the cutter blade and the cutter cradle at the half-cutting position perform the half-cutting operation with respect to the cut target. When both the cutter lever and the cutter cradle lever are operated by the user, the cutter cradle is moved to the full-cutting position and the cutter blade is moved so that the cutter blade and the cutter cradle at the full-cutting position perform the full-cutting operation with respect to the cut target.
Retractable printable medium support
A printable medium support for a printer comprises a support element to support a printable medium, wherein the support element is movable between a protruding configuration to support the printable medium, and a retracted configuration in which the support element is at least partially retracted in a first direction. The printable medium support comprises an actuating element to move the support element between the protruding configuration and the retracted configuration.
SHEET SUPPLYING APPARATUS AND PRINTING APPARATUS
A sheet supplying apparatus, which is capable of winding a sheet tightly, includes a driving unit configured to cause a roll including a wound consecutive sheet to rotate in a first direction for feeding the sheet or a second direction opposite to the first direction, a sensor that detects a leading end portion of the sheet separated from an outer circumferential surface of the roll, and a contact body that presses the outer circumferential surface. Before the sheet is fed, in a state in which the contact body presses the outer circumferential surface, the driving unit causes the roll to continuously rotate in the second direction until a detection cycle of the leading end portion by the sensor is less than a predetermined value.
